HELLPPP!!!! Drug Calculation

Published

how to calculation this 2 question:

-patient to receive 50mcg/hr for 24 hrs

pharmacy label:

Sandostatin 0.1mg/ml injection (Octreotide)

neat. IV bolus- inj neat over 3 mins. IV intermittent inf- dilute in 50-200ml D5 or NS & inf over 30 mins. IV cont inf (oesophageal variceal bleeding). Inf neat without dilution; also compat with NS. Refrigerate. Do not freeze.

>>> what is the rate of the infusion by continuous, should dilute or no need? final volume after dilution?

(because I was confused that the drug runs for 24 hrs is continuosly but why no need to dilute ?)

question 2:

- patient to have 8mg/hr for 24hrs for 2 days

Losec 40mg injection (Omeprazole)

IV bolus: recons 40mg with 10 ml diluent provided & inject over at least 2-5 min (max 4ml/min). Stable for 4hrs after recons. Do not add other solutions for IV infusion.

>>> what is the rate of infusion? how to dilute and how much? final volume after dilution?

Welcome to AllNurses! Ok we won't do your homework for you. We are willing to help you understand medication administration but no we won't just give you the answers.

What does your research show these meds are used for? I am not sure about the use of the word "neat" please explain.

Show us how you set up the problems for calculation. (I use ratio proportion but you probably are taught dimensional analysis?)

what I calculated was

question 1 :

drugs on hand > 0.1mg/hr

order > 50mcg/hr for 24 hrs

=50/1000mg

= 0.05mg/hr

vol.required = 0.05mg/0.1mg x 1 ml

= 0.5 ml

(need 0.5ml of sandostatin)

will dilute 1ml of sandostatin in 50ml of n.saline /D5

0.5ml needs 25ml of n.saline / D5 to dilute

rate : 0.5ml/hr in 25 ml of n.saline/ D5

question 2 :

on hand > 40mg (diluent in 10ml)

order > 8mg/hr for 24 hrs for 2 days

vol.required= 8mg/40mg x 10ml

= 2ml

rate: need 2ml/hr of omeprazole
